摘要
尝试用数字滤波器产生混沌密码序列 ,针对已有算法和它的一些改进算法存在内部状态间具有较强相关性的问题 ,提出了一种新的改进方法 ,通过合理选择系数 。
A kind of digital filter is used to generate chaotic cipher sequence. Then, a crucial fault of the method and its improved methods, a strong correlation between the internal states of the digital filters, is discussed. In order to overcome the fault, improved method is suggested which can generate some more pseudorandom chaotic cipher sequence by selecting proper coefficients.
